If you are a landlord in Ontario and a tenant has approached you about keeping an emotional support animal, you are not alone in feeling uncertain about what the law actually requires of you. Emotional support animals in Ontario sit at the intersection of two powerful pieces of legislation, and getting it wrong can expose you to a human rights complaint at the Landlord and Tenant Board or the Human Rights Tribunal of Ontario. This article breaks down exactly what the law says, what you can and cannot do, and how experienced property managers handle these situations in practice.
The short answer is this: Ontario landlords have very limited ability to refuse an emotional support animal when a tenant has a documented disability and a legitimate need. A "no pets" clause in a lease is already unenforceable under the Residential Tenancies Act (RTA, 2006), and the Ontario Human Rights Code (OHRC) adds a second layer of protection specifically for tenants whose need for an animal is tied to a disability. Understanding both laws is the only way to make sound decisions for your rental property.
What Is an Emotional Support Animal Under Ontario Law?
An emotional support animal (ESA) is an animal that provides therapeutic benefit to a person with a mental health or emotional disability. Unlike a trained service animal, an ESA does not need to perform specific tasks. Its presence alone is considered part of the person's treatment or coping strategy. Common examples include dogs, cats, rabbits, and birds, though in principle any species could qualify.
This distinction matters enormously for Ontario landlords. Service animals, such as guide dogs for people who are blind, are governed by the Accessibility for Ontarians with Disabilities Act (AODA) and are almost universally recognized. Emotional support animals occupy a different legal space: they are not formally certified or registered under any Ontario government program. There is no official ESA registry in Canada. Any website selling an "ESA certificate" or "ESA registration" is selling a document with no legal standing. What actually matters under the OHRC is whether the tenant has a disability and whether the animal is part of their accommodation needs.
At Blue Anchor, we see landlords make two common mistakes here. The first is treating an ESA exactly like a pet and applying a blanket refusal. The second is accepting any printed certificate from the internet as proof of need without understanding what documentation actually carries weight. Neither approach protects you.
Ontario Law on Emotional Support Animals: The RTA and the OHRC
Two laws govern how you must respond to an ESA request in Ontario, and they work together in a way that significantly limits a landlord's ability to say no.
The Residential Tenancies Act (RTA, 2006) makes "no pets" clauses void and unenforceable. Section 14 of the RTA is explicit: any provision in a tenancy agreement that prohibits or restricts the presence of animals is void. This applies to every residential lease in Ontario, regardless of what the agreement says. You can still take action if an animal causes damage, creates an unreasonable disturbance, or if a tenant or other occupant has a severe allergy, but you cannot simply enforce a "no pets" policy as written.
The Ontario Human Rights Code (OHRC) goes further. The OHRC prohibits discrimination in housing on the basis of disability. If a tenant requires an emotional support animal as part of managing a recognized disability, refusing to accommodate that need is considered discriminatory unless you can demonstrate that the accommodation would cause you undue hardship. Undue hardship is a high legal bar. Cost alone rarely qualifies, and inconvenience does not qualify at all.
Together, these two laws mean that a landlord who refuses an ESA request from a tenant with a genuine disability is exposed to a human rights complaint, potential damages, and orders to accommodate. The Human Rights Tribunal of Ontario can award general damages for injury to dignity, feelings, and self-respect, in addition to ordering the landlord to allow the animal.
What Can Ontario Landlords Actually Ask For?
This is where many landlords get confused. You cannot demand an "ESA letter" from a specific type of professional, and you cannot require the tenant to use a particular form. However, you are entitled to enough information to understand whether the accommodation request is legitimate. The OHRC guidance on this is clear: you can ask for confirmation that the person has a disability and that the animal is connected to that disability, but you cannot demand a full medical diagnosis or detailed health history.
In practice, a letter from a regulated health professional, such as a physician, psychologist, or registered social worker, confirming that the tenant has a disability and that an emotional support animal is part of their treatment or coping plan, is the standard documentation that carries real weight. That letter does not need to name the diagnosis. It simply needs to establish the connection between the disability and the need for the animal.
What you should not accept as meaningful documentation is a certificate purchased online from a non-regulated source. These documents have no standing under Ontario law. If a tenant presents one, it is reasonable to ask for a letter from their treating health professional instead. At Blue Anchor, we guide our landlord clients through exactly this conversation so they ask for the right information without crossing into territory that could be seen as discriminatory.
Can an Ontario Landlord Refuse an Emotional Support Animal?
In most cases, no. If the tenant has a documented disability and the animal is connected to that disability, refusing the request is likely a violation of the OHRC. There are narrow circumstances where a refusal might be defensible, but they are genuinely rare.
The most commonly cited exception is a severe, documented allergy in another tenant in the same building. If another resident has a life-threatening allergy to the specific animal in question, and there is no reasonable way to accommodate both tenants simultaneously, that may constitute undue hardship. Even then, you should explore every possible solution before refusing, including unit placement, HVAC adjustments, and scheduling arrangements.
A landlord's personal preference, concerns about resale value, or a general dislike of animals do not come close to meeting the undue hardship threshold. In our experience managing rentals across Belleville, Trenton, Cobourg, and Oshawa, landlords who attempt a flat refusal without a documented undue hardship reason almost always end up in a worse position than those who engage with the request constructively from the start.
Damage, Liability, and What You Can Still Protect
Accepting an emotional support animal does not mean accepting unlimited liability for whatever that animal does to your property. Ontario law still allows you to hold tenants responsible for damage caused by their animals, and you can document the condition of the unit before and after tenancy to support any claim at the LTB.
The standard lease includes provisions for tenant responsibility for damage beyond normal wear and tear. If an ESA causes damage to flooring, walls, or fixtures, you can pursue compensation through the LTB using an L2 application or by claiming against the tenant's last month's rent deposit, subject to the rules under the RTA. What you cannot do is charge a separate pet deposit, as Ontario law does not permit additional deposits beyond the last month's rent.
This is one reason we strongly encourage the landlords we work with to ensure their tenants carry renters insurance. At Blue Anchor, we offer a renters insurance program to our tenants that includes $1 million in liability coverage and $100,000 in pet liability coverage for approximately $30 to $42 per month. That coverage protects both the tenant and the landlord if an animal causes damage or injures someone on the property. You can read more about why we built our renters insurance program and how it works for our tenants.
Thorough tenant screening before a tenancy begins is also your best tool. A well-screened tenant with a strong rental history is far less likely to cause problems, with or without an animal. You can learn more about how Blue Anchor screens tenants to help landlords make confident placement decisions.
Handling Conflicts Involving ESAs in Ontario Rentals
Even when you have done everything right, conflicts can arise. A neighbour may complain about noise. Another tenant may claim an allergy. The animal may cause damage. Here is how to handle each scenario without creating legal exposure for yourself.
For noise or disturbance complaints, treat the situation the same way you would any other disturbance complaint. Document the complaint in writing, communicate with the tenant in writing, and give them a reasonable opportunity to address the issue. If the disturbance continues and meets the threshold for substantial interference with reasonable enjoyment, you can pursue an N5 notice under the RTA. The fact that the animal is an ESA does not give the tenant unlimited licence to disturb other residents.
For allergy complaints from other tenants, take them seriously and document everything. Seek medical confirmation of the allergy and explore all possible accommodations before concluding that the two situations are incompatible. This is a genuinely difficult situation and one where getting professional advice from a paralegal or lawyer familiar with Ontario tenancy law is worth the cost.
For damage, conduct regular property inspections as permitted under the RTA (with proper notice) and document the condition of the unit throughout the tenancy. If damage occurs, you have the right to pursue compensation through the LTB regardless of whether the animal is an ESA.
Practical Tips for Ontario Landlords Navigating ESA Requests
At Blue Anchor, we have developed a consistent approach to ESA requests that protects our landlord clients while treating tenants with the respect the law requires. Here is what we recommend:
- Respond to every ESA request in writing and acknowledge receipt promptly. Ignoring a request or delaying indefinitely can itself be seen as a failure to accommodate.
- Ask for a letter from a regulated health professional confirming the disability and the connection to the animal. Do not ask for the diagnosis itself.
- Do not accept online ESA certificates as sufficient documentation, but do not reject them aggressively either. Simply explain what documentation you need and why.
- Document the condition of the unit with photos and a written condition report before the animal moves in.
- Ensure the tenant has renters insurance that includes pet liability coverage.
- If you have genuine concerns about undue hardship, consult a paralegal or lawyer before refusing. A refusal without proper legal grounding is far more expensive than the cost of advice.
- Keep records of all communications related to the ESA request in case the matter ever goes to the Human Rights Tribunal of Ontario or the LTB.
If you are a landlord in Belleville, Trenton, Quinte West, Cobourg, Oshawa, or Picton and you want professional support managing situations like this, our Belleville property management and Cobourg property management services include handling exactly these kinds of tenant communications on your behalf.
Frequently Asked Questions: Emotional Support Animals in Ontario
Can I enforce a "no pets" clause against a tenant with an emotional support animal?
No. Under Section 14 of the Residential Tenancies Act, "no pets" clauses are void and unenforceable in Ontario. Even if such a clause were enforceable, the Ontario Human Rights Code would still require you to accommodate a tenant whose need for an ESA is connected to a disability, unless you can demonstrate undue hardship.
Does an emotional support animal need to be certified or registered in Ontario?
No. There is no official ESA certification or registration program in Canada. Online ESA certificates have no legal standing. What matters under the OHRC is whether the tenant has a disability and whether the animal is connected to that disability, typically confirmed through a letter from a regulated health professional.
Can I charge a pet deposit for an emotional support animal in Ontario?
No. Ontario law does not permit additional deposits beyond the last month's rent deposit. You cannot charge a separate pet deposit or an ESA fee. You can, however, hold the tenant responsible for any damage the animal causes through the LTB process.
What if another tenant in my building is allergic to the ESA?
This is one of the few situations where a refusal might be defensible, but only if the allergy is severe, documented, and there is genuinely no way to accommodate both tenants. You must explore every reasonable option before concluding the situations are incompatible. Get professional legal advice before refusing in this scenario.
Can I evict a tenant whose emotional support animal causes damage or disturbances?
You can pursue the same remedies available for any tenant whose animal causes damage or substantial interference with reasonable enjoyment. An N5 notice can be served for disturbances, and damage claims can be pursued at the LTB. The ESA status of the animal does not exempt the tenant from responsibility for their animal's behaviour or the damage it causes.
Final Thoughts
Emotional support animals in Ontario are a topic that trips up even experienced landlords because the rules come from two different pieces of legislation and the documentation standards are genuinely unclear to most people. The safest path is to take every ESA request seriously, ask for appropriate documentation from a regulated health professional, protect your property through insurance and condition reports, and get professional advice before refusing any request. A flat refusal based on a "no pets" policy is almost never the right answer under Ontario law.
